Just to be clear, MIMO does not only apply to LTE. MIMO can also be used, for example, with any of the 3G WCDMA schemes. I agree entirely with the point about antenna and device orientation, though. For MIMO to be effective, the propagation paths between transmitter and receiver, all of which share the same frequency channel, must be as uncorrelated as possible. Once you start seeing a dominant path emerging, the spectral efficiency of MIMO drops. It works best in pure Rayleigh channels.
